"Unhackable" Infineon Chip Physically Cracked
After gaining physical access to the chip, Tarnovsky still had to navigate the chip's software defenses. According to the Associated Press, Tarnovsky remarked that "This chip is mean, man--it's like a ticking time bomb if you don't do something right."
Does this mean that Infineon's flagship secure chip has been entirely compromised? Infineon was aware that a physical hack was possible, but a company representative notes that an attack of this sort would require resources beyond that of the typical cracker. Joerg Borchert, a vice president of security at Infineon, told the AP that, because this attack requires a combination of physical access to the chip, a smart hacker, and expensive equipment, "the risk is manageable, and you are just attacking one computer."
